RADIATOR.

Specification of Letters Patent.

Patented Nov. 10, 1914-.

Application filed October 15, 1913. Serial No. 795,432.

1 0 all whom it may concern;

Be it known that I, F RANK 0. BISHOP, a citizen of the United States, residing at Springfield, in the county of Sangamon and State of Illinois, have invented new and useful Improvements in Radiators, of which the following is a specification.

My invention relates to improvements in radiators and applies moreparticularly to the type of radiators composed of a series of hollow vertical sections.

An object of my invention is to provide a radiator in which the columns forming the radiator will be relatively large in cross section at the base of the sections, and which columns will be tapered to a restricted radiating surface at the top of the sections, whereby the air space between the vertical columns will be increased with the height of the radiator and the cold air near the floor readily heated, allowing room for expanslon as it rises, thus creating a draft constantly upward.

With the above and other objects in view, my invention consists in the novel construction and arrangement of parts hereinafter described, illustrated in the accompanying drawings, and pointed out in the appended claims.

In the drawings illustrating the preferred embodiment of my invention, like numerals of reference refer to like or corresponding parts throughout the several views.

In the drawings :-F igure 1 is a side elevation of a radiator illustrating the preferred embodiment of my invention. Fig. 2 is an end elevation of one of the sections of the radiator of my invention. Fig. 3 is a sectional view of one of the radiator sections taken on line 2-2 of Fig. 2. Fig. 4 is another sectional view taken on line 33 of Fig. 2

Referring now to the drawings, numeral 1 designates the end sections and numeral 2 the middle sections of a radiator, the end sections being provided with feet 3.

I prefer to provide the radiator of my invention with three vertical columns, designated as 5 and 4E, numeral 5 designating the two outer columns and numeral at the central column. The outer columns 5 are provided with large radiating surface near the base thereof, and. in order to accomplish this arrangement, the inner walls 6 of the outer columns 5 are tapered inward toward the outer wall, said taper increasing with the height of the radiator. thus restricting the radiating surface at the top. The side walls 7 of the middle sectionsare likewise tapered inward with the height, while the outer walls 8 are formed perpendicular with respect to the floor on which the radiator stands.

In the middle sections of my radiator it will be seen that the two side walls 7 of the vertical columns, together with the outer wall 8 will unite to form a cross section having three sides somewhat in the form of a letter U. and that the inner wall 6 which completes the section is in the shape of the letter V.

The end sections of the radiator conform to the shape outlined for the middle sections, with the exception that the walls forming the end of the radiator are preferably perpendicular. I prefer to use the usual method of uniting the sections of the radiator of my invention, and do not seek to cover same by Letters Patent.

From the foregoing description it will be readily manifest that I have provided a novel form of radiator which will provide the large amount of radiating surface near the base and which surface will be restricted with the height of the radiator, thus increasing the air space within the radiator with the height thereof.

While I have described the preferred embodiment of my invention, I do not wish to be limited thereto except for such limitations as the claims may import, as it is obvious that the details of construction and arrangement of shape may be varried in many ways. as. for instance. the radiator may be provided with a tapering central column 4:, or other cross connections may be provided.

Having thus described my invention, what I claim is 1. A radiator composed of a series of hollow vertical sections having two outer columns formed with large cross sections at the base of the sections and constantly decreasing cross sections toward the top of the sections. and a central column having approximately the same cross section at the base of the radiator as at the top, substantially as described.

2. A radiator composed of a series of hol- 10W vertical sections having two outer colcreasing air space toward the top of the umns formed with large cross sections at the radiator, substantialy as described.
